acitizen-of the United States, residing at .Des Moines, in the county ofPolk and State .oi'lowa, have invented 'a'certain new and useful Insolefor Shoes or? the like, of when the following visa specification.

I-The ohjectof my invention is to provide tionfixed thereto,- the partsbeing simple,

of athletic types-which are provided with rubber soles.

- Still a further object is to provide under the heel portion'of thefoot-e resilient pad orstrip of material which, is provided withoval-shaped grooves extended. only. part way through said pad forpermitting the resilient portion to be spread or moved to J positionWhere it will conform to-the underside of the heel of the foot. o

Still another object is .to provide heads which are formed'adjacent' tothe edgesofthe grooves-in the resilient'material, which ribs areada'pted'to co-ect or rest against the inner surface of the sole, of ashoe for preventing the possibleslipping of vthe insole within; the sl1oe,iorfrom having it crowd Ctowardsfthe toe of the shoe.

1 Still another object is'to provide an issole of substantially the sameshape as-the sole of the shoe, the resilient portion, however, beingprovided only under the heel portion ofthe insole, and being held in'position bymeans of the remainder of the insole, which is preferablymade'of a tough strip of: fiaterial such as leather or cloth.

A leather insole or strip of material; when it is used'with an athleticshoeserves'asa non-conductor of the heet which is usually exgeriencedwith shoes having rubber soles.

till another object'is to provide the resilient'portion of the insoledirectly helowv a The groovesl i permit the resilient pad-13 ,the heelof the iootso that .it may serve as a-heel or raised portion When. it.is: used in 'a'nathletio 'shoeg and -at thesame time serve as a cushionfor preifenting jars and shocks dueiofialkingrunning or jumping, or anyother exercise. a

"With these and other objects in View my invention consists in the,construction,

errangement and combination of the various parts of my dew icm-wherebythe; objects" contemplated are attained, as hereinafter 'Applieetionfiie i' my 25,-

,In the accompanying 'dratvings have used the reference numeral 10 toindicate m cs; pointed out imy on the line of FigureQ through the onordinary athleticshoe; which is provided I :with a sole 11 preferably ofrubber. I

It Will'be understood that in most athletic shoes practically no heel orraised portion for a heel is provided.

A My improved sole comp'rises-afstrip of trough material 12 preferablyof leather and substantially the outline of a shoe sole. The strip ofmaterial 12 maybe said to c'ontain two parts, a heel portion A .and asole portionB. 'f h Fixed to the underside of the heel portion A of thestrip of material 12' is. a resilient pad or-ciishion 13, preferably-ofrubber." The pad of resilient material 13-" is tapered from itsforwaidend slightly so as to pm, vide an. inclined portion between the heel,

-Th'e pad -13-is provided 'with'a plurality of grooves 14 which; areoval-shaped in cute line, and spaoed'one Within another, as clearlyillustrated in Figure2'of the draw-. ings; Each of the grooves 14: havethein-v set. forth;

to be easily compressed to conform to-the edges proyided Witha loead,15, the purp0s&,=-

of .Which will be- .hereinaft ern ore fully?" outline of theheel of thefoot and (at. the

same time serves as a cushion for-any sudden 16 between the'gro'oves 14will be spread or caused to 'fill'the gIQOVGSfll: when any presever,assoon as the pressure is releasedthe jar or shock; The portionof thematerial" sure isapplied upon the resilient pad.- 'Howpartsrwill'ret urnto their; normal position and thus serve esa cushion.)

The beads which project downwardly beyond the lower surface of the mainbody portion of the pad 13 rest upon the shoe sole and thusprevent theeasy slipping of the entire-insole within'the shoe orthe heel portionfrom crowding towards the toe and at,

the same time gives additional flexibility to the pad '13.

By providing the pad 18 below the heel portion A. of the strip ofmaterial 12- it not only serves as. a cushion forthe preventing of anyshocks or jars, but it also normally serves as a heel "for an athleticshbe.

The pad 13 is arranged so'that its edge, 'is flush with the edge of theheel portion of the strip-of material 12 so as to prevent its I edgebeing bent downwardly due to the pressure of the foot. thereon. The pad13 serves to make the cushion efiectfgreatest whereit' is 'most desired,that is, where the surface of the persons heelrests. The spread of thecontour of the foot.

The arrangementof the pad 'lilllush with ,the heel portion A of thestrip of material- 12 prevents such an undesired effect as hereinbetoredescribed.

Another advantage is the arrangement of the stripv o'fleatherwvhichcovers the entire shoe sole and serves as a non'conductor of heat in theathletic shoe. Another advantage of my lnsole and resilient cushion isthat a heel is formed and thus the breaking down of a persons arch dueto the no-heel't vpe of shoes is substantially eliminated. I

From the construction of the parts just described it will bescen thatmyinsole is very simple, can easily he slipped into or out of the shoe,and when used will be very com-' fortablc. It will be understood that mytype of insole may be placed in-the shoe at the time of manufacture ofthe shoe'and per;

inanently secured therein. v I

Some changes may be made in the construction and arrangement of theparts of my insole without depaiting from the real spirit and purpose ofmy invention, and it is my intention to cover by my claim, any mochfiedforms ofistruoture' or use of mechanical equivalents, which may bereasonably ineluded within its scope.

I claim as my invention;

An insole for shoes of substantially the outline of a shoe comprising astrip-of tough material, divided into two portions, a heel portion" anda sole portion and a resilient strip of -niaterial of substantially thesame outline as said heel'portion secured to the underside ot'said stripof tough material,

said resilient strip of material'having a plurahty or oval shapedgrooves-therein, said oval shaped grooves being spaced one within theother and being substantially the shape'of an inverted U in crosssection, the

materialbetween eachof the said last grooves being providedjwithcomparatively shallow] formed on the edges of said first groove, the

parts being so arrangetl thz'it the inaterial between said grooves willbe spreadoutand forced into said grooves when under pressure,

thus giving a cushioning eitect to any sudd n pressure applied upon theheel portion of said insole all for the purposcsstated. Des Mtines,Iowa, July 18th, 1921.
